- A simple synthetic method of a 1,3,5-triazine UV absorbent CGL-479 and its characterization
-
As a novel ultraviolet (UV) absorbent with excellent performance in UVA section (320 ~ 400 nm), 2-{2-hydroxy-4-[(octyloxycarbonyl)ethylideneoxy]phenyl}-4,6-Bis(4-biphenylyl)-1,3,5-triazine (CGL-479) was synthesized in a simple method with a total yield of 45.3% in four steps. Its outstanding UV absorption capability (λmax = 326 nm, ε max = 4.15×104 L·mol-1 ·cm-1), high thermostability [T5 (the temperature of losing 5% in weight) = 385 °C], and compatibility with polymer materials make it a potential substitute of the traditional UV absorbents.
